Just had our empeg mk II installed in my wife's 2000 Cabrio. Sounds incredible, of course. Used an Alpine 5 channel amp, with an Alpine 10" sub.
Found a decent install house in this area called Car Spa. They had heard of the empeg, and one gentleman had seen it at a show. Chris, the installation manager, seemed a bit sceptical of it at first, but when the job was done seemed quite impressed, both by the flexibility and the quality. Car Spa has a shop in Baltimore, also, if anyone in that area is looking for a shop.
Anyway the installation was done quite well, and everything looks quite professional. I'll have some pics later.
